IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 121,241, dated November 28, 1871.

To all whom it may concern:

Be it known that I, ALONZO FRENCH, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Lamps and Lanterns, and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use my invention, reference being had to the accompanying drawing which forms a part of this speciiication, and in which- Figure 1, Sheet 1, represents a lantern containing my improvement 5 Fig. 2, Sheet 2, a similar lantern, arranged for burning coal-oil; and Fig. 3, Sheet 3, a side light.

The said invention consists in the arrangement of the screw-thread by which the lamp or lantern is attached to its supporting-collar. It also consists in the construction of the skeleton stand.

The same parts are `denoted by the same letters in all the figures.

A in the drawing represents the stand or base, which is of open or skeleton form; and consists, usually, of an upper and a lower ring, united by arms a, a. To the upper ring b is secured, in any convenient manner, the oil-fountain B. Between the stand and fountain is the perforated ventilatorC, which also forms a rest for the globe D. The globe has a screw-thread, d d, formed on its outer surface, by means of which it is securely fastened' to the screw-collar E of the guards. This thread may be on any intermediate partof the globe, but must not be at the top or bottom edge thereof. rEhe stand A is constructed with one or more lugs or claws, F, and

with a spring-catch, Gr, to receive the bottom ring of the guard; and by means of these devices or their equivalents the guard is fastened to the stand. In Fig. 2, which represents a coaloil lamp, the perforated rest G is arranged above the oil-fountain. Fig. 3 represents a side-light, in which the screw-collar E is attached to a bracket or other stationary support.

I am aware that a screw-thread has been heretofore applied to the top or bottom of a glass lamp or globe, and to both the top and bottom thereof, for the purpose of supporting the same, by means of a screw-collar. By my improvement, however, the thread being arranged on an intermediate part of the surface, not only is the danger of breaking the glass diminished, but the globe is more steadily'supported. The skeleton stand may also be applied to a lamp, in which case it not only prevents the tilting of the lamp, but permits the light to shine without obstruction in a downward direction.

What I claim as `my invention, and desire to Witnesses M. F. WALTON, WM. R. WRIGHT.
